Abstract

In a pneumatically actuable surgical instrument, comprising a handle and a nozzle disposed on the handle gas-operated tool, a replaceable compressed gas storage, and a locking device for fixing the compressed gas reservoir to the handle in a working position in which the compressed gas storage is connected to a compressed gas channel, with the Tool is supplied with compressed gas, it is proposed to improve the handling of the compressed gas storage that the instrument further comprises an unlocking device for canceling the determination of the compressed gas storage in the working position.

Description

  • The invention relates to a pneumatically actuable surgical instrument comprising a handle, a pressure gas operated tool arranged on the handle, an exchangeable compressed gas reservoir and a locking device for fixing the compressed gas reservoir to the handle in a working position in which the compressed gas reservoir is connected to a compressed gas channel with which the Tool is supplied with compressed gas.
  • The pneumatically actuated surgical instruments described at the outset are frequently supplied with compressed gas with compressed gas reservoirs in the form of compressed gas cartridges so that a connection of the instrument to a compressed gas tube for supplying pressurized gas can be dispensed with and maximum handling of the surgical instrument is achieved.
  • The problem with the pneumatically operated instruments, which are equipped with a compressed gas storage, that at the end of the useful life of a compressed gas storage always a residual volume of compressed gas is contained, which escapes when removing the compressed gas storage from the instrument with a loud bang.
  • Pneumatically operated instruments according to the invention with a compressed gas reservoir are frequently used in the case of difficult interventions on the central nervous system. As an example, mention should be made of pneumatically operated bone punches, which allow bone or tissue material to be taken from the patient with a high level of force.
  • If a surgeon is still busy with a difficult intervention and in the background, the replacement of a compressed gas cartridge of a pneumatically operated instrument, it can easily lead to a fright of the surgeon and thus uncontrollable reactions.
  • In the case of pneumatically operated bone punches, it is particularly important that the punching force does not decrease during the procedure on the patient, since otherwise the shaft can remain fixed on the bone during engagement with the patient, while on the other hand the force of the punch is no longer sufficient for severing the bone material. Therefore, in this type of pneumatically operated bone punches, the function of the bone punch is automatically limited when a minimum pressure is reached or undershot.
  • This leaves in the compressed gas storage still significant amounts of pressurized gas left, for example, here is the remaining pressure gas pressure about 2 bar, a pressure sufficient to produce a more or less loud bang with each change of the compressed gas storage.
  • On the other hand, if after the completion of an operation of the pneumatically operated instrument and the compressed gas storage disposed therein, no extensive use has been made, it may also be that the compressed gas storage is still almost full. For further use of the instrument this must then be reprocessed, which necessarily requires the removal of the compressed gas cartridge. Here, the residual pressure in the compressed gas storage is still significantly higher, and again it is important that there is no danger to the staff when removing the compressed gas storage.
  • Object of the present invention is to make the initially described pneumatically actuated surgical instrument in the handling of the compressed gas storage easier and safer.
  • This object is achieved by a pneumatically actuable surgical instrument with the features of claim 1.
  • An essential element of the present invention is that the pressure accumulator the instrument can not be readily removed, but first the unlocking device must be operated before then released in a subsequent step, when the determination of the compressed gas storage in the working position, the compressed gas storage and can be exchanged.
  • Preferably, the unlocking device on a venting device, which is activated upon actuation of the unlocking device and transferred from a rest position to a first working position in which the compressed gas channel is connected to a vent opening. In a variant of the present invention, then the release of the compressed gas storage and the separation of the instrument and the replacement can take place.
  • In a further variant, it is provided that the venting device does not release the compressed gas reservoir in its first working position but continues to block it until the unlocking device is moved to a second working position in which the compressed gas duct is still connected to the venting port. In this variant, the compressed gas storage is released only in the second working position for separation from the instrument.
  • The measure allows that regardless of the remaining pressure in the Pressure gas storage sufficient pressure reduction, ie emptying the compressed gas storage takes place before the unlocking device is transferred to the second working position and the compressed gas storage can be separated from the instrument. An incorrect operation when changing the compressed gas storage is thus prevented.
  • By using an unlocking device, which in a preferred variant of the present invention, a ventilation device, a controlled venting of the compressed gas storage is possible, so that a momentary, associated with a bang venting of the compressed gas storage is omitted.
  • A certain remedy could be created by an extension of the thread in equipped with a screw compressed gas reservoirs, so that a removal of the compressed gas storage, for example, only over several 360 ° turns is possible, so that during the removal of the compressed gas storage of the surgical instrument, after a separation the compressed gas reservoir of the pressure gas channel of the instrument, sufficient time remains to reduce the pressure, as long as the compressed gas reservoir is still held with its threaded portion on the handle and its mating thread in engagement.
  • In such an approach, however, the user is not forced to first unlock in an upstream step and only then to initiate the actual step to replace the compressed gas storage. Also, no controlled venting is possible, and unscrewing the compressed gas reservoir from the surgical instrument would also not be easy to handle. In particular, the replacement of the compressed gas storage would be time consuming.
  • In contrast, the pneumatically actuable surgical instrument according to the invention can be supplied faster and easier to handle with a new compressed gas cartridge, and in particular can be derived in a preferred embodiment, as described below, the excess pressurized gas in a predetermined direction via a vent from the instrument ,
  • Although the inventive surgical instrument prevents in a preferred variant, that the compressed gas storage can be separated from the instrument without controlled venting, this function can be realized without complicating the handling of the instrument, especially without the instrument heavier and without it becomes more expensive to produce.
  • In particular, the pneumatically operable surgical instrument can also be combined with a bayonet assembly for the compressed gas storage, in which the disassembly process consists of a simple 120 ° rotation and thus can be carried out very quickly, without compromising the safety when replacing the compressed gas storage.
  • For the reasons mentioned above, it is advantageous if the surgical instrument according to the invention is equipped with a pressure sensor for monitoring the pressure in the compressed gas storage. This is preferably realized by monitoring the operating pressure in the compressed gas channel leading to the tool.
  • In addition, it is advantageous if the instrument comprises a display device for the current filling state of the compressed gas reservoir, which may also be coupled to the operating pressure in the compressed gas channel, so that the surgeon using the instrument is always oriented on the filling state of the compressed gas reservoir. In particular, it can be displayed in this way then, when the compressed gas supply in the compressed gas storage is too low for further use of the pneumatically operated instrument, so that he can immediately recognize the reason for the blocked function of the pneumatic instrument.
  • In a particularly advantageous embodiment of the pneumatically operated instrument is provided that the locking device and the unlocking device are formed as a mechanical unit. This simplifies insertion into and removal of the compressed gas storage from the instrument.
  • In this mechanical unit of locking device and unlocking additionally a display device for the current filling state of the compressed gas storage can be integrated, so that all three functions of the lock, the unlocking and the display of the filling state can be taken over by a mechanical unit. This has manufacturing advantages, and also the handling is simple and can also be used for a sensory display of the current filling state of the compressed gas storage, so that without eye contact with the display device, the surgeon information about the current filling state can be given.
  • In a particularly preferred embodiment of the surgical instrument according to the invention it is provided that the unlocking device with a single actuator from the rest position in the first working position and in the second working position is movable.
  • This simplifies the handling of the surgical instrument in the change of the compressed gas storage considerably, the security for the unlocking process is given by the fact that the actuator can be moved to a second working position via a first working position, in which already takes place a vent.
  • The user receives feedback about the progression of the emptying of the compressed gas reservoir via the hissing noise that occurs during the venting.
  • More preferably, the surgical instrument according to the invention on an exhaust duct, which receives spent compressed gas from the tool and dissipates into the environment. This applies, on the one hand, to the regular operation of the surgical instrument and can also be used for discharging the rest of the compressed gas from the compressed gas reservoir when changing the same, by virtue of the vent opening being in fluid communication with the exhaust air duct or being in fluid communication with the exhaust during the unlocking process Exhaust duct is brought.
  • A further reduction of the noise when changing the compressed gas storage can be achieved by either the vent or the exhaust duct itself is provided with a muffler.
  • In a further preferred embodiment of the surgical instrument according to the invention, it is provided that the locking device can be activated pneumatically, in particular by the compressed gas of the compressed gas reservoir.
  • Thus, the locking device is only active when the compressed gas storage is in fluid communication with the pneumatic unit of the instrument, and only in this state, a lock of the compressed gas storage is necessary. This prevents that in case of unfavorable insertion of the compressed gas storage, in which this does not get into fluid communication with the pneumatic device of the instrument, is prematurely locked and then a correction of the position of the built-in compressed gas storage is complicated.
  • According to a variant of the surgical instrument according to the invention, the compressed gas reservoir is held directly on the handle of the instrument. This can happen, for example, as in the US 2006/0151567 A described.
  • In a further alternative it is provided that the compressed gas storage is held in a housing on the handle of the instrument. Examples of this can be found in the DE 20 2007 006 801 U1 as well as in the US 2006/0151567 A , Here, the housing is formed as part of the handle. According to the invention, however, alternatively, the housing may be formed as a separate part and releasably fastened to the handle of the instrument.
  • More preferably, surgical instruments according to the invention have a sensor that checks the presence of a compressed gas storage in the working position on the handle of the instrument and optionally also displays.
  • The surgical instrument according to the invention preferably has a touch device with which the engagement of the compressed gas reservoir can be detected.
  • The sensing device may in particular be equipped with a mechanical or optical sensor.
  • Sampling can also be performed on the optional accumulator housing or accumulator mount, which will optionally mount the accumulator together on the handle.
  • Preferably, the sampling takes place at the compressed gas storage itself. In this case, the scanning can take place either on the outer circumference of the substantially cylindrical compressed gas reservoir, on its front side or, if appropriate, in the region of a shoulder of the typically bottleneck-like tapered end of the compressed gas reservoir with which it is connected to the compressed gas channel of the instrument.
  • As mechanical sensors pen-like sensing elements or hollow cylindrical elements are preferably in question. The pin-like sensing elements set on a punctual surface of the compressed gas storage, whether on the outer circumference, the front side or in the shoulder area.
  • The hollow cylindrical sensing elements, which may be formed fully or partially cylindrical, typically set on an annular surface in the region of the end face or the shoulder of the compressed gas storage.
  • However, pin-like or hollow-cylindrical scanning elements can also be used for scanning an optionally used compressed gas storage housing, holder, sleeve or the like.
  • It is also conceivable that the pin-like or hollow cylindrical sensing elements engage an adapter element with which the compressed gas storage is provided before it is connected to the handle on the compressed gas channel.
  • In addition, it is conceivable that the scanning takes place on a closure element of a compressed gas storage housing into which the compressed gas storage can be inserted before it is connected to the compressed gas channel of the handle.
  • For locking the compressed gas storage in its working position, a mechanical locking element is preferably used.
  • This preferably engages in its active position in a recess on the compressed gas storage itself, on the housing or other holder, a closure element of the housing or the holder or in a locking mechanism for such a housing, such a holder or the closure element.
  • The locking via the mechanical locking element is preferably effected pneumatically by the gas pressure supplied by the compressed gas reservoir, more preferably against the force of a spring-elastic element. As soon as the pressure provided by the compressed gas reservoir has fallen below a predetermined value, the locking element is transferred from its active position to an inactive position and the compressed gas reservoir is released for removal.
  • More preferably, the surgical instrument on a control device which releases the function of the tool at a predetermined, sufficiently high gas pressure in the compressed gas storage and locks the function of the tool at a low gas pressure. Such surgical instruments according to the invention can also be formed and used in particular as bone punches.
  • These and other advantages of the invention will be explained in more detail below with reference to the drawing of a preferred example. They show in detail:
  • 1 a surgical pneumatically operated instrument according to the invention in the form of a bone punch in a partially broken view;
  • 2 : a detail of the bone punch of 1 ;
  • 3 . 4 and 5 : A sectional view of part of the bone punch of 1 in different operating states; and
  • 6A to 6C : Circuit diagrams of a part of the pneumatics of the bone punch 1 to explain the in the 3 to 5 shown operating states.
  • 1 shows an instrument according to the invention in the form of a bone punch 10 with a pistol-shaped handle 12 and a pneumatically operated punching tool held thereon 14 ,
  • At his from the tool 14 spaced end points the handle 12 a connection device 16 on, over which a compressed gas storage 18 with the handle 12 is connectable. The compressed gas storage 18 becomes in this embodiment of an instrument according to the invention 10 together with a hollow cylindrical housing part 20 on the handle 12 mounted so that the connection between the handle 12 or its compressed gas channel (not shown here) and the compressed gas storage 18 is protected against mechanical effects.
  • In the in 1 shown operating state is the pressure in the compressed gas storage 18 dropped so far that with the pressure available in the pressure gas channel a safe working with the punch 14 is no longer possible and therefore the function of the bone punch 10 is blocked. To indicate to the staff the reason for blocking the punching tool 14 is at the handle 12 , adjacent to the connection device 16 , an indicator 22 provided, the word "empty" released in this mode and thus visible. This is accompanied by the fact that a locking element 24 out of engagement with a recess 26 on the housing part 20 stands and so the housing part 20 with the compressed gas storage 18 Can be separated from the instrument by turning the bayonet lock (not shown in detail).
  • As mentioned above, the function of the bone punch 10 blocked for safety reasons at a time, in addition to a significant residual pressure in the compressed gas storage 18 is available. To avoid that in this condition the compressed gas storage 18 without further ado of the handle 12 or whose compressed gas channel can be separated, engages a still held by the residual pressure in an activated position locking element 24 in a recess 26 at the top 28 of the housing part 20 one.
  • This operating state is described below with reference to an enlarged detail of the 2 explained in more detail.
  • The housing part 20 is with the handle 12 or its connection device 16 in the present embodiment with a bayonet lock 29 coupled, which in itself a quick replacement of the compressed gas storage 18 allowed. In the operating state shown the 2 is the locking element 24 in an inactive position in which it is disengaged from the recess 26 is; of the Residual pressure in the compressed gas storage 18 is reduced to a predetermined value, which preferably corresponds substantially to the ambient pressure. Only in this state, the bayonet lock can be solved with a rotary motion, the housing part 20 including the compressed gas reservoir held therein 18 from the handle 12 disconnect and the compressed gas storage 18 ultimately exchange.
  • Based on 3 to 5 the following is the sequence when changing a compressed gas storage 18 be described in more detail.
  • 3 shows a sectional view through the connecting device 16 of the handle 12 in an operating condition in which a fresh compressed gas storage 18 with the instrument 10 to be connected. The compressed gas channel 30 of the handle 12 is depressurized in this state. Consequently, one of the compressed gas channel is also 30 branching control channel 32 depressurized.
  • The control channel 32 is with the closed end 33 a cylindrical bore 34 in the handle 12 connected, in the longitudinally displaceable a control piston 36 is stored. The control piston 36 is by means of a coil spring 38 in the pressureless state of the control channel 32 against the closed end 33 the bore 34 pressed. That in the present embodiment with the control piston 36 integrally formed locking element 24 is in the inactive position.
  • The housing part 20 with a fresh compressed gas storage or cartridge arranged therein 18 Can now by bayonet lock with the connection device 16 of the handle 12 get connected.
  • The cartouche 18 is in the in 3 state shown at its end inserted into the connecting device 40 still with a seal 42 gas-tight and pressure-tight.
  • The compressed gas channel 30 of the handle 12 ends in the area of the connecting device 16 with a for piercing the seal 42 inclined against the axial direction ground hollow cylindrical end 44 , The pitch of the bayonet closure is chosen so that with the rotation during a closing movement of the housing part 20 the cartouche 18 so far in the connection device 16 of the handle 12 engages that end 44 the seal 42 completely interspersed and in the upper, open end 40 the cartouche 18 penetrates. At the same time, the outer circumference of the upper end 40 the cartouche 18 or, as shown in the present embodiment, one on the cartridge 18 screwed adapter sleeve 47 from a seal arranged in the connection device 46 captured, allowing a gas-tight connection between the cartridge 18 and the compressed gas channel 30 is made. This situation is in 4 shown.
  • The pressure of the cartridge 18 , For example, about 10 to 12 bar, now acts on the compressed gas channel 30 and the control channel 32 on the closed end of the hole 34 and push the control piston 36 against the spring 38 out of the inactive position. The with the control piston 36 integrally formed locking element 24 moves into the recess 26 of the housing part 20 and blocks the bayonet lock. The instrument 10 is now ready. A separation of the cartridge 18 from the handle 12 is not possible in this state.
  • If the pressure in the gas cartridge drops 18 as a result of the operation of the instrument to a predetermined pressure value, for example, about 2 bar, the control piston 36 in the hole 34 by means of spring force towards the closed end 33 the bore 34 emotional. The locking element 24 however, remains in an active position and engages, albeit only partially, in the recess 26 of the housing part 20 one.
  • In this operating state, the tool is blocked in its function and the display element is between the two positions "full" and "empty".
  • With the on the locking element 24 arranged slide 23 can be the spool 36 in the direction of the end position (second working position of the unlocking device), as in 3 shown, press, even in a first working position of the unlocking device, the in 5 is shown, a connection of the control channel 32 and thus also the compressed gas channel 30 and the gas volume of the cartridge 18 with a vent line 52 is manufactured and maintained and the residual pressure of the gas cartridge 18 can be reduced to ambient pressure.
  • For this purpose, the control piston 36 a central axial bore 54 on the from the control channel-side end of the control piston 36 from in the direction of the locking element 24 is designed as a blind hole. At the closed end of the axial bore 54 is a cross hole 56 provided, which is designed as a throttle.
  • The formation of the transverse bore 56 as a throttle prevents the flow of larger quantities of compressed gas when inserting and connecting a fresh cartridge 18 with the handle 12 and its compressed gas channel 30 ,
  • The transverse bore 56 ends on the outer circumference of the control piston 36 in a section 58 , of the seen on both sides in the axial direction over a seal 60 respectively. 62 against the residual volume of the hole 34 is sealed. The length of the section 58 in the axial direction of the control piston 36 is sized to the section 58 in fluid communication with the vent line 52 comes before the locking element 24 completely out of the recess 26 disengages. This allows a controlled venting of the compressed gas channel 30 as well as the cartridge 18 be initiated before the housing part 20 with the bayonet lock from the handle 12 can be separated.
